摘要： A liquid crystal composition includes at least one compound of general Formula I in an amount of 1%-30% by weight of the total weight of the liquid crystal composition, at least one compound of general Formula II in an amount of 5%-35% by weight of the total weight of the liquid crystal composition, and at least one compound of general Formula III in an amount of 10%-50% by weight of the total weight of the liquid crystal composition. The liquid crystal composition has an appropriate clearing point, an appropriate optical anisotropy, an appropriate dielectric anisotropy, as well as a higher voltage holding ratio, a higher transmittance, a good high-temperature resistant performance and a faster response speed, thus being suitable for display modes, such as VA, IPS and FFS. A photoelectric display device includes the liquid crystal composition.
